Bhishma said Thus addressed, the son of Parasara said to his son,-I shall explain to you the two paths, viz., the destructible and the indestructible, resting respectively upon acts and knowledge. Listen with rapt attention, O child, to me as I point out to you the place which is reached by one with the help of knowledge, and that other place which is reached with the help of acts. The difference between these two places is as great as the endless firmament.
